IP: tunneling


x x

x Tunneling means encapsulating data of one protocol type within x

x another protocol and sending it over a channel that understands the x

x encapsulating protocol. This particular tunneling driver implements x

x encapsulation of IP within IP, which sounds kind of pointless, but x

x can be useful if you want to make your (or some other) machine x

x appear on a different network than it physically is, or to use x

x mobile-IP facilities (allowing laptops to seamlessly move between x

x networks without changing their IP addresses). x

x x

x Saying Y to this option will produce two modules ( = code which can x

x be inserted in and removed from the running kernel whenever you x

x want). Most people won't need this and can say N. x
